An amino acid neurotransmitter is an amino acid which is able to transmit a nerve message across a synapse. Neurotransmitters (chemicals) are packaged into vesicles that cluster beneath the axon terminal membrane on the presynaptic side of a synapse in a process called endocytosis .
Many neurotransmitters are synthesized from simple and plentiful precursors such as amino acids, which are readily available and often require a small number of biosynthetic steps for conversion. Neurotransmitters are essential to the function of complex neural systems.
Norepinephrine is synthesized from the amino acid tyrosine by a series of enzymatic steps in the adrenal medulla and postganglionic neurons of the sympathetic nervous system, while the norepinephrine that functions as a neurotransmitter in the brain is produced in the locus coeruleus, located in the pons of the brainstem.

Monoamine neurotransmitters are neurotransmitters and neuromodulators that contain one amino group connected to an aromatic ring by a two-carbon chain (such as -CH 2-CH 2-). Examples are dopamine , norepinephrine and serotonin .
Neuropeptide Y. Neuropeptides are chemical messengers made up of small chains of amino acids that are synthesized and released by neurons.Neuropeptides typically bind to G protein-coupled receptors (GPCRs) to modulate neural activity and other tissues like the gut, muscles, and heart.

The fruit is also rich in antioxidants, electrolytes, and amino acids like tryptophan. One banana is also low in calories, with very little protein or fat, since it’s mostly water and carbohydrates.
The receptor can be activated by a range of simple amino acids including glycine, β-alanine and taurine, and can be selectively blocked by the high-affinity competitive antagonist strychnine. [2] Caffeine is a competitive antagonist of GlyR. [3] Cannabinoids enhance the function. [4]
